Heterocyclic glp-1 agonists

ABSTRACT

This disclosure relates to GLP-1 agonists of Formula (I): including pharmaceutically acceptable salts and solvates thereof, and pharmaceutical compositions including the same.

CROSS REFERENCE TO RELATED APPLICATIONS

The application claims the benefit of International Patent Application Number PCT/CN2020/109304, filed on Aug. 14, 2020; and International Patent Application Number PCT/CN2020/074537, filed on Feb. 7, 2020, each of which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

This disclosure relates to GLP-1 agonists, pharmaceutical compositions, and methods of use thereof.

BACKGROUND

Incretin metabolic hormones, including glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), are important in the regulation of glucose homeostasis. Medicaments targeting this family of intestinal peptides, such as GLP-1 agonists, have been shown to suppress glucagon production, decrease gastric motility, and increase satiety.

Diabetes mellitus refers to a group of metabolic disorders characterized by persistent hyperglycemia. The most common form, type 2 diabetes mellitus (T2DM) is an acquired condition that accounts for more than 90% of diabetes cases. Typical onset occurs in obese or otherwise sedentary adults and begins with insulin resistance. Though lifestyle changes can be useful in management of this disorder, patients with T2DM may be required to take anti-diabetic medications, including dipeptidyl peptidase-4 inhibitors, SGLT2 inhibitors, and sulfonylureas, among others.

In healthy individuals, the incretin hormones glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide 1 (GLP-1) provide tandem modulation of insulin secretory response to glucose ingestion. While this incretin effect is significantly diminished (if at all present) in cases of T2DM, GLP-1 retains insulinotropic properties, even as endocrine pancreatic response to GIP is effectively halted. As such, incretin mimetics and other GLP-1-based therapies can help stimulate insulin production in T2DM patients.

Pharmaceutical Compositions and Administration

When employed as pharmaceuticals, the compounds of Formula (I), including pharmaceutically acceptable salts or solvates thereof can be administered in the form of a pharmaceutical compositions. These compositions can be prepared in a manner well known in the pharmaceutical art, and can be administered by a variety of routes, depending upon whether local or systemic treatment is desired and upon the area to be treated. Administration can be topical (including transdermal, epidermal, ophthalmic and to mucous membranes including intranasal, vaginal and rectal delivery), pulmonary (e.g., by inhalation or insufflation of powders or aerosols, including by nebulizer; intratracheal or intranasal), oral or parenteral. Oral administration can include a dosage form formulated for once-daily or twice-daily (BID) administration. Parenteral administration includes intravenous, intraarterial, subcutaneous, intraperitoneal intramuscular or injection or infusion; or intracranial, e.g., intrathecal or intraventricular, administration. Parenteral administration can be in the form of a single bolus dose, or can be, for example, by a continuous perfusion pump. Pharmaceutical compositions and formulations for topical administration can include transdermal patches, ointments, lotions, creams, gels, drops, suppositories, sprays, liquids and powders. Conventional pharmaceutical carriers, aqueous, powder or oily bases, thickeners and the like may be necessary or desirable.

Also provided herein are pharmaceutical compositions which contain, as the active ingredient, a compound of Formula (I), or a pharmaceutically acceptable salt or solvate thereof, in combination with one or more pharmaceutically acceptable excipients (carriers). For example, a pharmaceutical composition prepared using a compound of Formula (I), or a pharmaceutically acceptable salt or solvate thereof. In some embodiments, the composition is suitable for topical administration. In making the compositions provided herein, the active ingredient is typically mixed with an excipient, diluted by an excipient or enclosed within such a carrier in the form of, for example, a capsule, sachet, paper, or other container. When the excipient serves as a diluent, it can be a solid, semi-solid, or liquid material, which acts as a vehicle, carrier or medium for the active ingredient. Thus, the compositions can be in the form of tablets, pills, powders, lozenges, sachets, cachets, elixirs, suspensions, emulsions, solutions, syrups, aerosols (as a solid or in a liquid medium), ointments containing, for example, up to 10% by weight of the active compound, soft and hard gelatin capsules, suppositories, sterile injectable solutions, and sterile packaged powders. In some embodiments, the composition is formulated for oral administration. In some embodiments, the composition is a solid oral formulation. In some embodiments, the composition is formulated as a tablet or capsule.

Further provided herein are pharmaceutical compositions containing a compound of Formula (I), or a pharmaceutically acceptable salt or solvate thereof with a pharmaceutically acceptable excipient. Pharmaceutical compositions containing a compound of Formula (I), or a pharmaceutically acceptable salt or solvate thereof as the active ingredient can be prepared by intimately mixing the compound of Formula (I), or a pharmaceutically acceptable salt or solvate thereof with a pharmaceutical carrier according to conventional pharmaceutical compounding techniques. The carrier can take a wide variety of forms depending upon the desired route of administration (e.g., oral, parenteral). In some embodiments, the composition is a solid oral composition.

Suitable pharmaceutically acceptable carriers are well known in the art. Descriptions of some of these pharmaceutically acceptable carriers can be found in The Handbook of Pharmaceutical Excipients, published by the American Pharmaceutical Association and the Pharmaceutical Society of Great Britain.

Methods of formulating pharmaceutical compositions have been described in numerous publications such as Pharmaceutical Dosage Forms: Tablets, Second Edition, Revised and Expanded, Volumes 1-3, edited by Lieberman et al; Pharmaceutical Dosage Forms: Parenteral Medications, Volumes 1-2, edited by Avis et al; and Pharmaceutical Dosage Forms: Disperse Systems, Volumes 1-2, edited by Lieberman et al; published by Marcel Dekker, Inc.

EXAMPLES

The invention is further described in the following examples, which do not limit the scope of the invention described in the claims.

Schemes 1-3 delineate exemplary methods for preparing compounds of Formula (I) and intermediates useful for the synthesis of Formula (I) compounds.

Referring to Scheme 1, ester I1 (wherein R⁴ is as defined for Formula I;

is selected from the group consisting of:

wherein R⁵, R⁶, and R⁷ are as defined for Formula I) is subjected to a metal-catalyzed cross-coupling reaction (e.g., Suzuki coupling using Pd(dppf)ClCH₂Cl₂ in the presence of potassium carbonate) with an appropriate coupling partner such as a reagent with Formula (Ring C)-Y (wherein Ring C is as defined for Formula I; and Y is B(OH)₂ or boronate ester such as BPin) to provide compound I2. Optionally when Ring C is a saturated heterocyclyl, I1 can be coupled with a reagent of Formula (Ring C′)-Y wherein Ring C′ is a partially saturated heterocyclyl, followed by hydrogenation (e.g., with palladium on carbon) to afford I2. As a non-limiting example, when Ring C is tetrahydropyran-4-yl, I1 can be coupled with (Ring-C′)-Y of formula:

Subsequent reaction of I2 with I3 (e.g., in the presence of NaH in DMF) provides compound I4, whereupon hydrolysis of the ester group under standard conditions (e.g., with LiOH in H₂O/THF) affords compound I5. Amide coupling of I5 with NHMePh under standard conditions (e.g., HATU and Hunig's base) provides 16. The reaction of 16 with a reagent I6b (wherein the dashed curve L^(x) represents a C₂₋₅ alkylene optionally substituted with a C₁₋₆ alkyl, wherein the C₁₋₆ alkyl is optionally substituted with from 1-3 independently selected R¹) under basic conditions (e.g., KHIMIDS, DMPU) then provides I7, wherein Ring D′ is a C₃₋₆ cycloalkyl which is optionally with a C₁₋₆ alkyl, wherein the C₁₋₆ alkyl is optionally substituted with from 1-3 independently selected R^(f). As a non-limiting example, I6b can be

wherein the Ring D′ in the corresponding product is

Treatment of I7 with a hydroxylamine source (e.g., NH₂OH·HCl in EtOH under reflux) followed by reaction with a phosgene equivalent (e.g., CDI (e.g., in the presence of DBU and DMSO at 80° C.)) provides compound I8. Hydrolysis of the amide group in I8 (e.g., with KOH in CH₃OCH₂CH₂OH at e.g., 125° C.) provides compound I9.

Referring to Scheme 2, carboxylic acid I10 wherein R³ is as defined for Formula I is subjected to amidation with an ammonium source (e.g., NHE₄C₁) under standard conditions for amide-bond formation (e.g., with a carboxyl activating agent such as HATU, in the presence of a base such as Hunig's base) to provide compound I11. Under dehydrating conditions (e.g., with TFAA and pyridine at room temperature), I11 is converted into compound I12 which is subjected to acidic conditions (e.g., MeSO₃H in THF at e.g., 65° C.) to afford compound I13. Compound I13 is then coupled with I13b (wherein R² and R³ are as defined for Formula I) in a Michael-type addition to provide compound I14 (e.g., in the presence of NEt₃ in a polar protic solvent such as EtOH at elevated temperature such as 70° C.), following protection of the amino nitrogen with the appropriate protecting group (i.e., Pg). As a non-limiting example, Pg can be a carbamate protecting group such as Boc. Under basic conditions, I14 is subjected to an intramolecular Dieckmann-type condensation (e.g., with t-BuOK at room temperature) to provide I15. Condensation of protected hydrazine compound I16b (wherein Ring A is as defined for Formula I; and each Pg is a nitrogen protecting group such as a carbamate protecting group like Boc) with I15 then affords compound I16 (e.g., upon treatment with TFA in DCM at room temperature, followed by treatment with Py-HCl in EtOH under reflux). Reaction between I16 and I17b (e.g., in the presence of a polar aprotic solvent such as DMA) provides compound I17, whereupon treatment under acid (e.g., MeSO₃H, THF, 60° C.) followed by reprotection of the secondary amino group (e.g., with Boc₂O) provides compound I18, wherein Pg is a nitrogen protecting group such as a carbamate protecting group like Boc. Compound I18 is then coupled with compound I18b wherein Q¹-Q⁵ are as defined for Formula I and X is a halo (e.g., —Br or —I) or pseudohalo (e.g.,—OTf) (e.g., under typical Ullman coupling conditions known in the art) to provide compound I19. As a non-limiting example, the coupling can be carried out in the presence of CuI, K₂CO₃, and

in NMP (e.g., at 130° C.). Removal of the nitrogen protecting group (i.e., Pg) on I19 (e.g., under acidic conditions such as HCl in dioxanes) then provides compound I20.

Referring to Scheme 3, coupling of I20 with I9 under standard amide bond forming conditions (e.g., in the presence of a carboxyl activation agent such as HATU (e.g., in a polar aproptic solvent such as DMF)) provides compound I21, which is a compound of Formula I.

It will be apparent to a person of ordinary skill in the art that in the synthetic sequences delineated above (see Schemes 1-3), reactive groups such as NH₂, NH, and OH can be protected with appropriate protecting groups, followed by a deprotection steps at appropriate stages of the synthesis. It is also within the purview of a person of ordinary skill in the art to conceive variations of the foregoing methods to synthesize other Formula I compounds. For example, by exchanging I6b with other electrophilic reagents, compounds with other L³-C(R^(8a)R^(8b))-L⁴-R⁹ groups can be obtained. As another example, by replacing 116 with other appropriate reagents, compounds with other L² moieties can be obtained.

Example A: cAMP Assays

Activation of GLP-1 receptor is known to stimulate cyclic AMP (cAMP) production in cells which indicates primary coupling to the G_(αs) subunit of the G protein heterotrimeric complex. Evidence suggests signaling through G_(αs) induced cAMP stimulation elicits the desired pharmacological response regarding insulin release from pancreatic β-cells.

Method 1: To optimize functional activity directed toward G_(αs) coupling, a CHO-K1 cell line developed by DiscoverX stably expressing the GLP-1 Receptor is used. Cells expressing GLP-1 receptor are plated in a 384-well microtiter plates and incubated overnight at 37° C. with 5% CO₂ to allow the cells to attach and grow. Media is then aspirated from the cells and replaced with 15 μL Hanks Balanced Salt Solution (HBSS)/5 mM Hepes: 0.5 mM IBMX 0.1% BSA (pH 7.4) [Stimulation Buffer]. Plated cells are resuspended in Stimulation buffer and five microliters (5 μL) of the suspension is added to previously generated compound sample stocks at 4×final concentration in Stimulation Buffer are then added to the cells and allowed to incubate at 37° C. for 30 or 60 minutes.

After incubation the assay signal is generated using a europium chelate-labeled cAMP tracer which competes with cAMP for binding sites on a cAMP-specific monoclonal antibody labeled with ULight™ dye. When antibodies are bound to the Eu-labeled cAMP tracer FRET transfer between the Eu chelate and ULIght™ labeled antibodies is detected. Free cAMP produced from stimulated cells competes with the Eu-cAMP tracer for binding to the ULight-mAb causing a decrease in the TR-FRET signal in a dose dependent manner.

The method for detection of cAMP using using the Eu-chelate technology requires incubation with Eu-cAMP tracer solution+ULight-anti-cAMP solution for one hour at room temperature. Microplates are read following signal generation with a PerkinElmer Envision instrument utilizing TR-FRET signal detection. Percentage activity is calculated using the following formula:

% Activity=100%×(mean RLU of test sample−mean RLU of vehicle control)/(mean RLU of MAX control−mean RLU of vehicle control))

Method 2: To optimize functional activity directed toward G_(αs) coupling, a CHO-K1 cell line developed by DiscoverX stably expressing the GLP-1 Receptor is used. Cells expressing GLP-1 receptor are plated in a 384-well microtiter plates and incubated overnight at 37° C. with 5% CO₂ to allow the cells to attach and grow. Media is then aspirated from the cells and replaced with 15 μL 2:1 Hanks Balanced Salt Solution (HBSS)/10 mM Hepes: cAMP XS+Ab reagent. Five microliters (5 μL) of previously generated compound sample stocks at 4×final concentration in assay buffer are then added to the cells and allowed to incubate at 37° C. for 30 or 60 minutes.

After incubation the assay signal is generated using enzyme fragment complementation (EFC). In EFC, the enzyme B-galactosidase is split into two complementary portions (EA and ED). The fragment ED is fused to cAMP and in the assay format competes with endogenous cAMP for binding to a cAMP specific antibody. Activated B-Gal is formed when exogenous EA fragment binds to free ED-cAMP (not bound to cAMP specific antibody). Activated enzyme levels are detected through conversion of B-gal chemiluminescent substrate which generates a detectable luminescence signal and read on standard microtiter plate.

The methodology for detection of cAMP using EFC requires incubation with 20 μL of cAMP XS+ED/CL lysis cocktail for one hour followed by incubation with 20 μL cAMP XS+EA reagent for three hours at room temperature. Microplates are read following signal generation with a PerkinElmer Envision instrument utilizing chemiluminescent signal detection. Compound activity is analyzed using CBIS data analysis suite (ChemInnovation, CA). Percentage activity is calculated using the following formula:

% Activity=100%×(mean RLU of test sample−mean RLU of vehicle control)/(mean RLU of MAX control−mean RLU of vehicle control))

Method 3: Activation of GLP-1 receptor is known to stimulate cyclic AMP (cAMP) production in cells which indicates primary coupling to the G_(αs) subunit of the G protein heterotrimeric complex. Evidence suggests signaling through G_(αs) induced cAMP stimulation elicits the desired pharmacological response regarding insulin release from pancreatic β-cells.

To optimize functional activity directed toward G_(αs) coupling, a HEK293/CRE-Luc cell line developed by HDB stably expressing the GLP-1 Receptor was used. 200×concentration of compound working solutions were prepared (Agilent Technologies Bravo) with 1/2 log serial dilution in 384-well Echo LDV plate (Labcyte, Cat #LP-0200). 50 nL/well 200×concentration of compound working solutions were moved to 384-well white low volume plate (Greiner, Cat #784075) using Labcyte ECHO550. 1×10⁵ cells/mL HEK293/GLP1R/CRE-LUC(HD Biosciences) cell suspensions prepared with assay buffer [DPBS containing 0.5 mM IBMX(Sigma, Cat #15879) and 0.1% BSA(GENVIEW, Cat #FA016-100g)], 10 μL cell suspensions were added to each well of previous generated assay plate which already contains 50 nL compound at 200×concentration using ThermoFisher Multidrop Combi (1000 cells/well). Seal the plate and incubate at 37° C. with 5% CO₂ for 30 min.

After incubation the cAMP assay signal was generated using cAMP dynamic 2 Kit (Cisbio). 5 μL cAMP-d2 working solution was added to each well, followed with 5 μL Anti-cAMP antibody-cryptate working solution added to each well using ThermoFisher Multidrop Combi. Incubate at room temperature for 1 hour protected from light. Read the fluorescence at 665 nm and 615 nm with Reader PerkinElmer EnVision.

Example B Rat Pharmacokinetics (PK) Studies

Pharmacokinetics (PK) study was conducted on male Sprague Dawley (SD) rats by two delivery routes: intravenous (IV) and/or oral gavage (PO). Rats in IV route (n=3) were free access to food and water. Rat in PO route (n=3) were fasted overnight and fed at 4 hours post dosing. Test article was formulated in solution for IV route and solution or suspension for PO route, respectively. On the day of experiment, test article was administered via vein (e.g. foot dorsal vein) injection (commonly at 0.2 to 1 mg/kg and 2 mL/kg) for IV route or via oral gavage (commonly at 5 to 100 mg/kg and 10 mL/kg) for PO route, respectively. Blood samples were collected via serial bleeding at ˜8 time points from 0.083 to 24 hrs post dose. Approximately 150 μL of blood/time point was collected into K₂EDTA tube via tail vein. Blood samples were put on wet ice and centrifuged to obtain plasma samples and plasma samples were submitted to LC-MS/MS for sample analysis. Pharmacokinetics parameters, including clearance (IV), area under the curve (AUC) and oral bioavailability (F %), etc. were calculated by non-compartmental model using WinNonlin.

Exemplary compounds of Formula (I) (e.g., certain compounds of Formula (IE)) were tested using the protocol above. The compounds tested exhibited plasma clearance (L/hr/kg) in the range of 0.20 to 1.60 (e.g., between 0.20 to 0.80 (e.g., between 0.30 to 0.50); or between 1.00 to 1.60 (e.g., between 1.20 to 1.60)); and volume of distribution (L/Kg) in the range of between 0.40 to 0.70 (L/Kg).

Example C Glucose Tolerance Test in Non-Human Primate (NHP)

Cynomolgus monkeys (2.5-6.0 kg) were individually housed in stainless steel cages for the duration of the study under a controlled environment that was set to maintain a temperature of 18-26° C. and relative humidity of 30-70%, a minimum of 10 air changes/hour. A time-controlled lighting system was used (light 7:00 AM-7:00 PM) to provide a regular 12-hour light/i 2-hour dark diurnal cycle. The monkeys were provided with 3 meals per day consisting of 100 g of proprietary normal diet in the morning 9:00-10:00, one regular fruit (150 g) in the afternoon 14:00-15:00, and 100 g of proprietary normal diet in the afternoon 16:00-17:00. Drinking water was provided ad libitum. All animals were conducted baseline ivGTT and then selected animals assigned into pre-set groups base on the baseline ivGTT insulin AUC and their body weights.

The general study outline is presented in the table below:

Day: −7 −6 −5 −4 −3 −2 −1 1 2 3 4 5 6 7 8 9 Acclimation Phase Treatment Phase

Prior to the start of the study, animals were acclimatized for 1 week. On day 1, all animals were dosed with vehicle via IV injection for 5 min prior to IV glucose challenge. On day 9, all animals were dosed with either vehicle or compound via IV injection for 5 min prior to IV glucose challenge.

The ivGTT was conducted on day 1 and day 9, respectively. The overnight fasted animals were anaesthetized (Zoletil 50, intramuscularly, 5 mg/kg initial dose, and then maintenance dose at 2.5-5 mg/kg if needed).

5 min after the compound or vehicle dosing, the animals were intravenously injected with 50% glucose at a dose of 0.5 g/kg (1 mL/kg) for 30 seconds via the saphenous vein or the appropriate peripheral vein. The whole blood samples (1.2 mL) were collected into EDTA-K2 tubes from a peripheral vein at the following time-points: −6 (prior to compound dosing) and 1, 3, 5, 10, 20, 40 and 60 mins after glucose challenge.

The collected blood samples were stored under wet-ice and then centrifuged at 3500 rpm, 4° C. for 10 min within 60 min. The collected plasma samples (0.5 mL each) were stored in a freezer set to maintain−80° C. until analysis for glucose, insulin and C-peptide.

For test compound groups, approximately 1.0 mL of whole blood was collected into EDTA-K2 tubes from saphenous or cephalic vein at each time point of IVGTT on day 9. The collected blood samples were maintained on wet ice until centrifugation. Plasma was separated by centrifugation at 3500 rpm, 4° C. for 10 minutes within 60 minutes of collection. Statistical analysis of the data was completed using GraphPad Prism (version 9, GraphPad Software Inc, La Jolla, Calif.).

Exemplary compounds of Formula (I) (e.g., certain compounds of Formula (IE)) were tested using the protocol above. Specifically, a test compound was iv injected into healthy NHPs at the dose selected from 0.03 to 0.30 mg/kg (e.g., dosed at 0.05 mg/kg). Following the procedures described above, a 2.0 to 6.0 fold (e.g., 3.0 to 5.0 fold) insulin secretion was induced in ivGTT, and a 10% to 40% (e.g., 30% to 40%) increase in glucose clearance rate was observed.
